John Turner, from the Association of Electoral Administrators, has used a series of interviews (BBC radio, Scotland on Sunday) to warn that only people who were registered in 2006, or who decide themselves to add their details near the start of an election, will be able to vote in a snap general election.

Remember: If GB the PM calls an election, and you weren't registered in 2006, you have six days to request and return a "rolling registration" form from the elections folks at the Council House in Coventry. Make sure you can vote, as if it returns a majority government, you only have this chance every 4 years!
